I've seen the attachments getting through most of them are viruses. The attachments typically named as:

http://www.xxx.com.zip" CLASS="ASPForums" TITLE="WARNING: URL created by poster. - http://www.xxx.com.zip" CLASS="ASPForums" TITLE="WARNING: URL created by poster. - http://www.xxx.com.zip or mailto:xxx@xxx.com.zip" CLASS="ASPForums" TITLE="WARNING: URL created by poster. - xxx@xxx.com.zip

I've added the following attachments keywords:

*.zip
*.com.zip

But they're not working. The attachments still slip through. Anyone has any idea of how to list keywords in Attachments blacklist to effectively block those emails?

Thanks

Can you please let us know what version of SpamFilter ISP you are using? Please note that versions earlier than v2.0.1.306 have the following bug:

// New to VersionNumber = '2.0.1.306';
{TODO -cFix : Attachment filtering was not working if keyword list was empty}
